I just finished assembling my Chumby Guts Kit and was able to power it up fine. The tutorial intro program was running just fine. Then it suddenly stop. No screen. Nothing. Dead.

I have checked the power supply. Fine.

I have checked power coming to the daughtercard. Fine.

I have checked power to the Chumbilicial to the main board. Fine.

This is the extent of my electronics training. Any suggestions to help diagnose this problem would be greatly appreciated.
